WAN Inbound Bandwidth It allows you to set the connecting rate of data input for WAN.
For example, if your ADSL supports 1M of downstream and
256K upstream, please set 10000kbps for this box. The default
value is 10000kbps.
WAN Outbound Bandwidth It allows you to set the connecting rate of data output for WAN.
For example, if your ADSL supports 1M of downstream and
256K upstream, please set 256kbps for this box. The default
value is 10000kbps.
Reserved Bandwidth Ratio It is reserved for the group index in the form of ratio of
reserved bandwidth to upstream speed and reserved
bandwidth to downstream speed.
Enable UDP Bandwidth
Control
Check this and set the limited bandwidth ratio on the right
field. This is a protection of TCP application traffic since
UDP application traffic such as streaming video will exhaust
lots of bandwidth.
Outbound TCP ACK
Prioritize
The difference in bandwidth between download and upload
are great in ADSL2+ environment. For the download speed
might be impacted by the uploading TCP ACK, you can
check this box to push ACK of upload faster to speed the
network traffic.
Limited_bandwidth Ratio The ratio typed here is reserved for limited bandwidth of UDP
application.
